Andrea M. Maestas


Andrea M. Maestas is a partner in the New York and San Diego offices of Lewis Brisbois and a member of the Medical Malpractice and Healthcare Practices. Andrea has over a decade of experience defending physicians, hospitals, behavioral health facilities, and medical groups in malpractice and related claims throughout California and New York. She typically handles complex and catastrophic cases, including adult and pediatric neurological deficits, severe orthopedic injuries, paraplegia, and death. In addition to medical malpractice, Andrea represents long-term care facilities against elder abuse, negligence, and premises liability claims; and hospitals in employment discrimination and harassment disputes.

Prior to joining Lewis Brisbois, Andrea was an attorney at prominent defense firms in New York and California. She represented healthcare institutions in malpractice actions as well as hearings under the New York Family Healthcare Decisions Act, mental hygiene matters, and nursing home discharge appeal hearings. She has prepared and argued several substantive motions including in limine motions for trial, post-trial motions, summary judgment, and pre-answer dismissal motions. She has Second Chair trial experience and extensive experience in settlement negotiations, mediations, and arbitrations. She also mentors associates through all phases of pre-trial workup of medical malpractice and general liability matters.

During law school, she served as a Judicial Intern for the Honorable Steven R. Denton (Ret.) with the San Diego Superior Court. She also served as Chief Articles Editor of the TJSL Law Review, and competed in national moot court competitions with the TJSL Moot Court Honor Society. Prior to law school, Andrea worked in the health care field in Arizona and Nevada where she developed a love of medicine and saw how important it was for health care providers to have quality counsel they could depend on. 

Andrea takes great pride in developing cordial relationships with adversaries because it often yields significant advantages for clients with reduced litigation costs. She also keeps herself informed of the changes in regulations impacting healthcare and workplace liability from coast to coast. In her leisure time, she enjoys traveling, sailing the San Diego Bay, and spending time outdoors with her husband and two young boys.
